Well what can I say about shared hosting? Shared Hosting is for newbies and for startups. When you are new to the Internet world, you use shared hosting for hosting your site. A handful of people share the same physical server where it only takes few heavy sites to eat up all the provided resources making your site suffer.
Moving to VPS Hosting is logical once you have outgrown as a company or as a community on the Internet. VPS Hosting are ‘expensive’ and ‘very difficult to manage’ are some of the common myths. One can acquire VPS Hosting services for as minimum as $15 per month from vendors like DreamHost.
VPS hosting—Virtual Private Server Hosting—is a virtual space on a very powerful machine. It is like a small computer inside a supercomputer dedicated to your site. Unlike Shared Hosting, here you get full access to the promised resources. No other Webmaster with a heavy site can use your resources. Your site is going to run to the best of its potential until and unless you overload your VPS Hosting by hosting more and more sites on it.
